Intonation

Changes in fundamental frequency during the course of an utterance. Intonation carries information that is not provided by the stream of consonants and vowels. It might tell the listener whether the sentence is a question or a statement, or whether more will follow. Intonation may also signal differences in meaning or in attitude.
